"There is no doubt but that the making of Steel was known and practiced by the early Greeks probably several centuries before the birth of Christ. There have been discoveries of pre-historic forges and smelters evidently used for the making of iron and steel and it is certain that implements made of these materials dates back to antiquity. As to the methods of making the steels of antiquity there is little known, but it is quite probable since iron has a strong affinity for carbon that in the forging of the iron it's contact with the carbonaceous fuel would absorb carbon with the result that this iron would prove harder than usual. The next step was probably the accidental discovery that this iron could be hardened by dipping in water. Such iron, or we call it steel, would undoubtedly make the superior tools of the time, but the art of metal cutting did not really begin until the age of machinery which dates back only about a century and quarter, and it is in this age that the real development of metal cutting began"--Page 1. |
